I tested it and it works (Windows Vista 64 bit, fresh install of newest XBMC)

I suggest following:
-at top of list should be linked subtitles sorted by downloads DESC, following unlinked subtitles sorted by downloads DESC
-linked subtitles should be visually different from unlinked (color or text which says "unlinked" or something similar)
-Season + Episode information for TV series

Nice work.
But the plugin is working only if you have a video locally stored on XBOX (on internal disk). If you select video from smb share then it does not work and returns error on plugin.
And it would be nice if user could select preferred language.

Trouble is to be able to display the second label (column) on the right (with downloads & cds) I had to enable the genre sorting, which obviously controls how the entry are sorted (asc or desc). I might be able to do something though, as in prefix the "linked" entries with something like "[L]" or "[Linked]" which should make them appear hmmm probably at the botom, I'll think about it. I might be able to do something with colors though for the second column.

I was also thinking to move the movie name to the top right corner (some skins like PMIII are able to display that) and display in the list the release, might be more useful, we'll see how it goes.

I don't have any seasons / episodes, but what I could do is get the information and display it in the Movie Info panel (on an entry press "i" key). If you have an example I might change a version so you can try it.

I don't know about the SMBs I thought if XBMC is able to browse for the file it will return the URL and I can use that to read the file - I might check it sometime, I don't share files over the network.

For the subtitle location, I was thinking to add a propery (btw, see the Plugin Settings, that's where you can select the prefered languages) where to save the subtitles with 3 options - movie dir, ask (you are presented with a dialog to navigate to the save location) or the XBMC subtitle custom directory (http://wiki.xbmc.org/?title=Videos_Settings#Subtitles), sometime soon, I don't know when...

my copy of casino royal is labeled 007 - Casino Royale.avi the sub downloaded was named Casino Royale(2006).srt

currently it will DL subs but it doesnt rename them to match my media files name and thus when i play a movie i have to search the movie folder and force it to load the subs alternately i can rename them manually to make them load automattically but does sublight have the option to rename the .srt to the medias name?

if it does not i would like to add that as a feature request if possible.

Sorry for my late response on my earlier comment about an error result on the XBOX. I've had to reinstall XBMC twice, then I unexpectedly came across an XBOX that's better than the one I had and configured that one. Hens the delay...

When I select a movie file to search subtitles for I get an error. I've enabled error logging and searched for the lines where the error occurs. Somehow Sublight can't find the file I selected earlier event hough the path is correct. I'm running the 20678 SVN version for the XBOX. The new XBOX and fresh installation generates the exact same result as the XBOX installation on my old XBOX.
